AI Thread Summary
The discussion focuses on finding theoretical isochrones for a lab report on the ages of star clusters M15 and H+chi Persei. The original source, Seiss, is currently unavailable, prompting the search for alternatives. One participant suggests using a different data source, although it requires labor-intensive data processing to extract the necessary information. There is interest in developing a Python script to streamline this process. The thread aims to assist others facing similar challenges in accessing theoretical isochrones.

I am currently doing a 2nd year lab report and need some theoretical isochrones to work out the age of some clusters, M15 and H+chi persei (Double Cluster).

I was going to use Seiss: http://www-astro.ulb.ac.be/~siess/server/iso.html

But it doesn't seem to be online :(

What alternatives are there?

Any help would be greatly appreciated.

I found the data here http://stev.oapd.inaf.it/cgi-bin/cmd it is rather laborious to strip the data calculate the relevant colour index and plot it so I might make a python script to do it.

I hope this will be of use to anyone else who has the same problem and comes across this thread via the search function.
 
I am certainly intersted in that Python script!
 
Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
